How do I create complete Material color palette with shades 90-900, with accent shades, from a single color?

I need color shades 90-900 with A100, A200, A400, A700 accent shades, to define Angular Material Theme.

Other than that, how to include the original color in the palette? Most of the time, generated color palette doesn't include the original color.

Use like HCT(hue=sourceColor.hue, chroma=48.0, tone=t).toArgb(), where t={0,10, 20,...} corresponding to {A1000, A900, A800,...}

Another question of interest is how the original Material Design color palette was generated; was a similar approach as HCT taken there?

The method I say is the original generation method. But in the current palette we don't have the concept of A1000,... We only have "color roles", such as primary, primary container, they can't be accurately mapped from the legacy A400,... If you have read the source code, you will find it's relation to background color, contrast curve, and so many things, which can't be represented by A1000,...
